Answer:
I cannot say much without a lot of background, but I know that p makes 90 degrees when it intersects m and n, and that they do not necessarily have the same length, because it does not specify.
Step-by-step explanation:
43 as you substitute 6 in place of x, and then get 36+6+1=43

One method you can use to solve this problem is by setting up a proportion.
12 cups/28 oz = 18 cups/? oz
You'll want to cross multiply 28 by 18, which equals 504. Then divide 504 by 12 and you'll get the answer 42 ounces of beef broth.
Answer:
A) 9 percent of the variation in Days is explained by Size.
Step-by-step explanation:
A) 9 percent of the variation in Days is explained by Size.
r ², the coefficient of determination, which is the correlation between the dependent variable and the set of independent variables.
So since r = correlation coefficient= 0.3, therefore so r ² = 0.09 =9%
Therefore, 9% of the variation in Days can be explained by Size.
B) autocorrelation is likely to be a problem.
This is not possible.
C) the relationship between Days and Size is significant.
To have a significant relationship the value of r ² between 0 and 1 needs to be close to 1. r ² = 9% is closer to 0 and this indicates the regression model does not fit the data well.
D) larger accounts usually take less time to pay.
This is incorrect as relationship is a positive relationship which means more size tend to more days.
9 percent of the variation in Days is explained by Size is therefore the only conclusion we can get from the information.
